Product Summary
The ISO122U is a precision isolation amplifier incorporating a novel duty cycle modulation-demodulation technique. The signal
is transmitted digitally across a 2pF differential capacitive barrier. With digital modulation the barrier characteristics do not
affect signal integrity, resulting in excellent reliability and good high frequency transient immunity across the barrier. Both
barrier capacitors are imbedded in the plastic body of the package.The ISO122U is easy to use. No external components are required for operation. The key specifications are 0.020% max
nonlinearity, 50kHz signal bandwidth,and 200μV/°C VOS drift. A power supply range of ±4.5V to ±18V and quiescent
currents of ±5.0mA onVS1 and ±5.5mA on VS2 make these amplifiers ideal for a wide range of applications.
The ISO122U is available in 16-pin plastic DIP and 28-lead plastic surface mount packages.Parametrics
